STONE-SAWING- MACHINE.

Specification of Letters Patent.

Patented Oct. '13, 1908.

Application filed February 6, 1908. Serial No. 414,469..

To all whom it may concern:

Be 1t known that LARELI JONES, a citizen of the United States, and aresident of Oolitic, in the county of Lawrence and State of Indiana,have invented va new and Improved Stone-Sawing Machine, of which thefollowing is a full, clear, and exact description.

The invention relates to stone-sawing machines using rotating drums andendless traveling wires passing over the drums and serving to cut thestone.

The obj ect of the invention is to provide a new and improvedstone-sawing machine, arranged to permit of conveniently and quicklyadjusting the wires in the desired position relative to the stone forcutting the latter into pieces of the desired width.

The invention consists in the construction and combination of parts tobe fully described hereinafter and particularly set forth in the claims.

Reference -is to be hadto the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures, and in which Figure l is a sideelevation of the improvement; Fig. 2 is a plan view of the same; Fig. 3is an enlarged transverse section of the improvement on the line 3 8 ofFig. 4; Fig. 4 is a sectional side elevation of the same on the line 4-4of Fig. 3 and Fig. 5 is an enlarged cross section of the improvement onthe line 5-5 of Fig. 4.

The endless wires A, for cutting the stone B into pieces of suitablewidth, pass around drums C and C', having their shafts D and D journaledin suitable bearings arranged on the main frame E of the stone-sawingmachine. On the shaft D is secured a pulley F, connected by a belt Grwith other machinery for imparting a rotary motion to the drum C, thuscausing the wires A to travel, the lower runs-of the wiresy cutting thestone B, as indicated in Fics. l and 2.

The drums C and 3 are alike in construction Vand each is arranged indetail as follows: On the shaft D or D are secureda plurality of centersH, preferably made in sections fastened together by bolts H', H2, asplainly indicated in Fig. 4, and on the rims of said centers H, arelongitudinallyextending rails I, preferably in the form of angle ironsfastened to the rims of the centers H by bolts J, The rails I are spacedequidistant apart and are arranged in Va circle and engaged by bearingsK formed on the rims K, preferably made in sections fastened together bybolts K2. By the arrangement described, any one of the rims K can bereadily adjusted on the rails I in the direction of the axis of thedrum, and after the desired adjustment is made, the rim is fastened inplace on the rails I by clamping bolts L. By reference to Fig. 4, itwill be noticed that the bolts L extend in slots formed by a pair ofrails I, the said pairs of rails being arranged diametrically oppositeeach other and at right angles to the line of division of the rim K.Now, by the arrangement described, the operator on loosening the bolts Land K2, can conveniently shift the corresponding rim K on the rails I inthe direction of the axis of the drum, so as to bring the correspondingwire A, which passes over the said rim K, into the desired positionrelative to the stone B. Each of the rims K is preferably provided inits peripheral face with grooves for the passage of the correspondingwire A.

From the foregoing it will be seen that the construction of each drum Cor C is very simple and permits convenient and readyadjustment of therims K carrying the wires A, so that the wires can be brought into thedesired relation relative to the stone B to be sawed.

It is understood that by the improvement described the drums C and C canbe made of large diameters without unduly increasing the weight of thedrums; and large diameter drums are desirable to obtain as muchfrictional Contact between the .drums and wires as possible, to preventthe wires from slippingV on the drums.

In order to keep the wires taut, tightening sheaves N engage the upperruns of the wires adjacent to the driven drum C, as plainly indicated inFigs. l and Q; the tightening sheaves N being journaled in suitablebearings N held vertically and transversely adjustable on the frame E.Now by the use of the large diameter drums C, C and the tighteningsheaves N, the wires A are prevented from slipping, and hence theefflciency of the sawing machine is increased.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

l. A drum for a sawino machine, comprising a shaft, a plurality ofcenters attached to the said shaft, rails ranging in the direction ofthe axis of the druni and secured to the peripheral faces of the saidcenters, sundry of the rails being arranged in pairs to forni a slot,the pairs being disposed dianietrically opposite each other, a riininade in sections fastened together, and clamping bolts engaging thesaid pairs of rails and the rini to adjustably secure the latter on therails.

2. A druni for a sawing machine, provided with longitudinal rails,sundry of the rails being arranged in pairs, to forni a slot, the lpairs being diainetrically opposite each other, a rini made 1n sectionsfastened together, and clamping bolts engaging the said i pairs of railsand the rini, to adjustably .se-

cure the latter on the rails.

A drinn for a sawing machine, provided With longitudinal grooves, a rimmade in sections fastened together, and clamping bolts engaging thegrooves, and the riln, to adjustably secure the latter on the drum.

In testimony whereof I have signed my naine to this specification in thepresence olf two subscribing witnesses.
